DIE FoR MAKING AXES.

SPECIFICATION forming part of Letters Patent No. 402,937, dated May '7,1889.

Application filed Fehruary 20, 1889- $erial No. 300,530. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM C. KELLY, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in Dies forMaking Axes; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in dies forforming axes, such as described in an application for Letters Patent,Serial No. 300,440, filed by me February 19, 1880.

In the application referred to there is described an ax in which theblade is tapered gradually from its cutting-edge toward the eye, andcompressed or cut away each side of its center to form a welldefinedstep; and the object of my present invention is to provide dies withwhich an ax such as described can be quickly and economically formed.

In the accompanying drawings, Figure 1 represents a a perspective viewof one of the pair of dies embodying my invention, and Fig. 2 a similarview of the other die, while Fig. 3 represents a cross-section, taken atthe line w a: of Fig. 2, of the two parts of the die in contact.

Similar letters of reference denote like parts in the several figures.

A represents one'die and B the other, each being hollowed out orrecessed in a gradual wedge shape on the line from a to b, increasing indepth in the direction of the arrow, the blade of the ax being formed ata and the butt or head at b. The dies are transversely recessed at c toprovide an opening or recess for the eye-pin used in forming the eye ofthe ax, and from about the point (I to the two points a 6 there areformed raised portions f f, leaving that portion of each die containedwithin the boundaries of the lines d 6 lower than the portions f f,which latter, beginning on the line 6 g, are raised to a comparativelyhigh extent and continue horizontally or in slightly-decreasing heightuntil intersecting a pronounced step or short curved line, It,connecting with or intersect ing the line 6 d, and such raised portionsf gradually curve downward to form a junctture with the eye or headcavity D, as seen at i, so that a blank compressed between the dies A Bwould produce an ax such as I have hereinbefore described as forming thesubject-matter of another application for Letters Patent filed by me.

In the use of my improved dies I take a suitably-formed pole and bit,and when heated to the proper degree subject it to compression betweenthe dies A and B, the effect of which is to produce an ax having ageneral wedge shape or taper from the cutting-edge toward the eye orbutt, with a central raised portion or fulcrum increasing in height anddecreasing in width as it approaches the butt or eye, and having on eachside of such raised portion or fulcrum depressions or sunken portions,which, beginning at the juncture with the central raised portion, sinkabruptly, preferably in a short curve, and then extend horizontally orin a slightly-oblique direction toward the edge of the ax.

It will be understood that dies involving the general features of myinvention may be designed for making hatchets, as well as axes, as thegenus or broad idea consists in providing the cavity which forms theblade with the raised portions f, which, in using the dies, produce thedepressions and leave the central rib or fulcrum, hereinbefore referredto, the latter rising comparatively abruptly in contradistinction to agradual taper or inclination from the highest point to the oppositeedges or sides of the blade.

Having thus described my invention so that those skilled in the art towhich it pertains can fully understand the same, what I claim as new,and desire to secure by Letters Patent, is

1. A two part die for making axes or hatchets, each part having in itsworkingfaee a cavity corresponding with the general shape of theimplement to be formed, and

provided with raised portions f, such as In testimony whereoflaffixniysignature in shown and described. presence of two witnesses.

2. A two-part die for making axes or hatchets, each part having in itsworking- \VILLIAM C. KELLY.
